Does the Herz P1 Smart Scale need to be on a hard floor for accurate readings?

I keep mine on a hard floor all the time, so I can’t compare directly, but I did try it once on a rug just to see and the numbers were all over the place. Not just weight either, the body fat percentage seemed off too. I think it’s the scale shifting slightly on softer surfaces, even if you can’t see it moving. I would not trust it on carpet. The tiled bathroom floor is probably fine. I don’t think you’re overthinking it, just keep it on the tile and you should be good. It’s been consistent for me as long as I use it in the same spot.

I have used mine in a few different rooms and the carpet definitely changes the numbers. I do not think it is you. Hard floor gives me consistent readings, carpet gives me readings that jump around for no reason. I would just keep it on the tile and not trust it anywhere else.

Carpet is the culprit, not you. I moved mine between the hallway and a rug once and the difference was enough to make me stop trusting it for a few days. The body fat numbers especially seemed to shift around on the soft surface, which made the whole scan feel pointless.

I keep mine on a hard floor now and just accept that it needs that stable base. It is annoying if you want to weigh in a hurry somewhere else, but the consistency is worth the extra few steps to the bathroom. I would say treat the carpet readings as roughly correct at best and don’t overthink the exact numbers from those sessions.

Somehow I get worse readings on tile than on my hardwood floor.

I keep mine on a hardwood floor and it’s been pretty steady for me. The one time I tried it on a yoga mat just to see, the numbers were all over the place. I’d say the surface matters more than people think, but the tile should be fine for you.

I’d say the surface definitely matters more than people think, but not always in the obvious way. I’ve had mine throw weird numbers on a flat tile floor just because my weight shifted slightly while stepping on. The carpet just amplifies that. If you’re chasing consistent readings, find one spot and stick with it, regardless of what’s under it.

Carpet is probably the problem, but not for the reason you think. I had mine on a bath mat for a while and it would bounce around by a pound or two between weigh-ins. Moved it to the hallway and it settled down. The tile should be fine, assuming it’s not flexing or anything. These things use little sensors in the feet and if the surface gives even a tiny bit, you’re not getting a stable reading. A rug in a bedroom is going to be worse than a flat, hard tile floor.

That said, you’re also dealing with a scale that measures a lot more than just weight. If you’re stepping on it at different times of day, different hydration levels, or after a workout, the body fat and water numbers will shift on their own. Even the heart rate stuff gets weird if you’re not holding still.

I’d say keep it on the tile. Pick one spot, make sure it’s level, and stop moving it around. If the numbers are still jumping around after a week of consistent placement and timing, then maybe you have a calibration issue. But I’d bet on the carpet being the variable. It doesn’t take much to throw those sensors off.

I put mine on a folded towel once and the numbers were all over the place, so I just stick to the tile now.

Carpet is always going to mess with any scale, that’s not really a Herz thing. But the bigger thing is consistency. If you’re moving it between tile and carpet, you’re basically changing the setup every time, so of course the numbers are going to bounce around.

Tiled floor is fine, just make sure it’s not sitting on a grout line or anything. I keep mine in the hallway on hardwood and it’s been stable. I don’t think you need to overthink the surface as long as it’s firm and level. The carpet is probably just throwing off the initial weight reading before the sensors settle.

If you’re tracking trends, just pick one spot and stick with it. Use the same spot every morning and the data will make way more sense than chasing exact numbers on different floors.

I think tile is the way to go if you want the numbers to feel stable. I tried mine on a rug once and it gave me a reading that was like two kilos off from what the tile said a minute later. That was enough for me to just leave it in one spot and not bother moving it around.
